Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, JOHN W. .GOCHER, a citizen of the United States, residin in the city of. J ohnstown, in the county of ambria and State of Pennsylvania, have invented certain new and useful Improvements in Coke-Oven Construction; and I do hereby declare the followin to be a full, clear, and

exact description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to coke-oven con struction and particularly to externally fired ovens of the by-product type.

The brick or other refractory material used in the construction of ovens of the character mentioned and of the combustion chambers thereof, which for convenience of description herein I will call the superstructure, is subjected to intense heat, causing a considerable degree of expansion, and one of the objects of my invention is to provide means for allowing .for the expansion of that portion of the structure mentioned, independently of the latform and the metal structure by whicii the latter is supported, without causing difficulties or defects in the construction, and a further object of my invention is to rovide means for the free and effective circuation of air beneath the combustion chambers and adjacent parts, to prevent their deteovens upon a platform in such manner that the expansion of the superstructure will take place thereon, and in anchoring the central part of the lower portion of the superstructure to the latform, in order that the expansion on sit or side-thereof may be uniform.

Italso consists in forming ducts or pass es for the circulation of air below the co 'ng and combustion chambers, to protect them and the oven supports by keeping them cool and preventing undue expansion or contraction.

Referring now to the four sheets of drawings forming part of this'specification and in which similar characters indicate correspond ing parts:Figure l is a vertical section of a series of coke ovens taken on the line II of Fig. 2. Fig. 2 is a section through the combustion chamber and the coke ovens on the line 11-11 of Fig. 1. Fig. 3 is a top lan view of a portion of the supporting platform with parts broken away to more clearly show the manner of construction. Fig. 4 is a vertical transverse section of the supporting platform on the line IVIV of Fig. 3. Fig. 5 is a vertical longitudinal section on the line V-V of Fig. 4. Fig. 6 is an enlarged detail view showing more clearly the manner of constructing the air ducts beneath the platform.

The base of the structure is composed of transverse I-beams 1 and longitudinal I- beams 2, the former being connected by angles 3. Above the base, Z-bars 4 extend in a transverse direction with reference to the beams 1 and serve as-supports for the platform 5. i The Z-bars are so placed that ventilating ducts are formed between them,

and openings are left between their lower flanges for the passage of air. These openings are covered by damper-plates 6 for the greater part of their length, spaces being left however, between the ends of adjacent damper-plates to admit air from the spaces immediately beneath, between the I-beams. The air passes along these ducts between the Z-bars, through the openings 7 at the ends of the bars and into the box 8 between the I-beains at the end of the structure, said box being formed by means of short I-beams 9 connecting two of the other I-beams. The air then passes from the box through the openings 10 and out through the exhaust pipe 11. The function of the damper-plates 6 is to allow a given quantity of air to enter the ducts between the Z-bars at each of the openings between the damper-plates, the capacity of the ducts between the'Z-bars. being suflicient to carry off all of the air thus admitted, thereby providing an effective circulation. Plates 12 are riveted to the lower flanges of the end I-beams and serve to prevent the escape of air in that direction, and channels 13 and 13 inclose the Z-bar structure, the latter transversely across the ends of, and the former parallel with the Z-bars.

Above the latform 5 is the masonry work 14 through which pass the flues 15, connecting with the air chambers 16. In the side walls of the air chambers 16 are ports 17 to admit air into the combustion chambers 18 to cause the combustion of the gas therein, which gas is supplied from the pipe 28. The vertical ports 19 connect the combustion chambers 18 with a series of vertical flues 20.

In the regular operation the burning gases 29, embedded in the brickwork and secured to the platform. This channel-bar serves to anchor the upper portion of the central part of the structure so that the sliding mo tion, due to the expansion of the brickwork, will be distributed equally 1011 either side thereof, and the fines 15 are so located with reference'to the connecting passages below that the cumulative effect of the expansion of the brickwork will cause the said lines to register substantially exactly with the connecting passages mentioned. When the ovens are new and cold, these passages bear the relation to each other shown in Fig. 1 of the drawings; in other words they are slightly out .of aline'ment, in a cumulative manner to allow for their expansion when heated.

.the bricks located therein.

A regenerative chamber 30 contains a pile of brick, built up in the usual manner shown, and the air entering saidchamber coming into contact with the loosely piled bricks whichhave been heatedin the manner hereinafter described, is itself heated before it passes through the fines into the combustion chambers.- A chamber similar to chamber is located at the opposite side of the series of ovens, and the products of combustion passing from the combustion chambers on one side of the battery, enter the chamber at the opposite side and impart their heat to The operation is then reversed after the usual method, thereby utilizing the-heat imparted to the.

bricks by the products of combustion for,

heating the incoming air as-it is caused to enter the regenerating chamber, first at-one side of the battery and then at the other.

In order to provide for anymovcment of the iron base composed of I-beams 1 and 2. sand seals 31 are employed. Owing to the effective system of cooling which I have described, there will however be but a slight sliding movement at this point. Plates 32 extend around the lower outer cdge'of the flue section 33, and to these are connected when first starting assess angles 3 and 34. Air-ducts 35 beneaththe re,- generating chambers are connected with the said chambers by the ports or passages 36.

Although I have shown and described my improvements in considerable detail, I do not Wish to .be limited to the exact construc tion specified, but may usesuch substituas are embraced within the scope of my invention, as pointed out in the claims.
